Can I dual boot lubuntu 21.10 and windows 7 64 bit,32 bit

Solution 1:

Let's go through your questions individually:

Q. Is my cpu x64?

Yes. Intel reports the Atom N2600 is a 64-bit CPU.

Q. Can I dual-boot Lubuntu 21.10 and windows 7 32 bit?

Yes. The minimum system requirements for Lubuntu are difficult to find and will vary wildly based on what you plan on doing with the OS, but a basic installation of 20.04 will consume about 340MB of RAM. 21.10 will likely be somewhere close to that number as well.

What you may want to do is first boot into a Live Session to see how well the OS runs on your computer. If it's all good, then use the Installer to set up a dual-boot environment. If it's not quite what you're looking for, consider trying one of the other light-weight Ubuntu flavours, such as Ubuntu MATE or Xubuntu.
