Puppy Linux is made for old machines and generally just works. You can boot it up on a live USB and see what you think. Lots of flavours to choose from.

Considering that you’re planning to use this with family members who aren’t tech savvy, and as you’re essentially new to Linux yourself, I would suggest something like Zorin OS. The familiarity and ease of use should help you get started fairly quickly, even for newbies. There are a lot of other great distros, of course, some of which were mentioned here, but the learning curve for those can be just a bit steeper. As someone who’s essentially the “tech guy” of the family, believe me when I say you don’t want them to keep bugging you about questions or tech help because they “don’t understand” Linux. You want something that you just install and leave be.

Speaking of something that you can just install and leave, this isn’t strictly Linux, but a great OS to use for non-tech savvy family members is Chrome OS. Get Chrome OS Flex, install it on an old laptop, give it to your family members and call it a day. I’ve had success with it for some of my family members who’ve wanted to revive old laptops. It’s a lot more limited than full featured desktop operating systems, of course, but it’s perfectly suitable for the basic stuff. Best of all, it’s so easy to use that you usually wouldn’t even have to play tech support for your family for it.

I’d like to do something similar on my Pentium 3 box. Maybe Debian with a really light WM would be a good fit, maybe IceWM? It only has 512MB of RAM though so I might have to go even lighter than Debian. I also have an Athlon XP box with 2GB of RAM, but that’s too new to be fun. :p

Not a Linux power user, still very much new although I’ve done a bit of distrohopping before.
I loaded Fedora with KDE on an old laptop from 2012-13ish last weekend. Been having a good, smooth run with it so far so that’s where my vote goes. However, the memory specs you indicated for your family’s hardware might be tough.

My favorite very light is peppermintOS, I think you may have to go back to version 10 for 32 bit though.

I’ve said my peace about distro and desktop environment in another comment, but to answer the piece about what you can do as compared to Windows, Linux can do the vast majority of all your daily tasks. There are a couple of big sticking points, generally.

Microsoft products, i.e. Microsoft Office. There are alternatives available in the Linux space that do a great job and are good enough for probably 95-98% of people, but there are cases where they don’t quuiiiite match up. Formatting PowerPoints, for example. You may save a *.pptx from LibreOffice and a colleague will open it in Microsoft PowerPoint and it doesn’t look the same at all.

The other major software suite that keeps people in Windows is Adobe. Photoshop? Lightroom? Premiere? Not available on Linux. Again, there are alternatives, but they’re never quite as good. I say this as a photographer that runs 100% Linux all the time, I miss my photo editing software! I used Capture One, but the same principle applies. There’s no Linux release, and you can’t get it running on Linux no matter how much you tinker.

The third biggest sticking point is gaming. You can game on Linux. It’s better now than ever. I run AAA brand new releases on my PC, and again I’m 100% Linux. BUT! It does frequently require a little more elbow grease to get working than people are used to, and often times you can never get it to work 100% as well as it would in Windows.

Sorry for the big wall of text. But finally I just want to say, none of this is to dissuade you from putting Linux on those machine. Quite the contrary! I want you to be aware of what the pitfalls may be, so you can look out for them. I’d hate for you to go in expecting everything to be 1:1 with Windows, only for something to not work and it feel like a bad experience in the end.

since you’re a noob, idk if this will be very helpful to you, but

i used debian with awesomewm on an old pentium 4 from 2004-2005 and it was pretty fast! like a modern low-end computer. but you’d have to configure it to be noob-friendly/have patient users. i don’t mind it cuz i enjoy tinkering, but i imagine it could be very frustrating for other people.

i’d give you my awesomewm config (i configured it to be super minimal, but also familiar, as i was trying to create a desktop environment that could be used on older machines), but unfortunately my desktop no longer has a power supply, so i can’t access it :')

I’ve used Debian on an old netbook with an Intel Atom and onyl 2GB RAM. The experience wasn’t so bad but web browsing was definitely a pain. Video calling and watching YouTube (Firefox) was very sluggish and annoying to deal with. It’s fine for working with documents and watching low resolution videos locally but that’s about it.

I’ve also tried antiX but a lot of the defaults were annoying. If you (or your family members) can deal with it, then it’s probably the best lightweight Linux distro out there.

are there any linux distros that might work becasue im a noob who uses windows so im very lost. any tips or suggestions or something would be great.

In this case, I recommend just leaving your family members to do their own thing. From my experience, it is very hard to manage other people’s Linux issues if you don’t have decent knowledge on it yourself. If they don’t want to upgrade, that’s their problem. Not yours.

I’d suggest Linux mint Debian edition, at least for the 32bit machine. Many distros have stopped supporting 32bit lately.

It should be fairly user friendly.

There are some distros out there intended for low power machines, but usually you’ll be fine installing whatever distro you want and using a lightweight desktop environment for it. Any distro running a DE like Xfce or LxQt should feel pretty decent on older hardware.

Void’s xfce desktop release is awesome for old hardware but it takes a bit to setup.

I vote Ubuntu, I started as a complete noob about 10 years ago with them and at first it was frustrating and tough, but now everything is just done for me, software updates, sure! I all the sudden want to want a windows-type application, sure! I love that it comes with Firefox, which from what I’ve read should make your family safer from the initial launch of the browser, no matter where the site they want to reach.

Puppy Linux runs on a potato of any architecture and is super user friendly (grandpa certified)! Only 300 MB or so. https://puppylinux-woof-ce.github.io/

Anything with Xfce or MATE, such as Mint Xfce or MATE

Lubuntu!
