I found something about installing Windows 95 from floppies in
***this thread***To load Win95 from diskettes you need one boot disk like dos 7.1 boot disk and a disk set of the Win95 cab files.Disk 0 is for all the loose files left after copying the balance from disk one up.Disk 1 is Precopy1 file.Disk 2 is Precopy2 and Cab2,disk 3 is Cab3,Disk4 is Cab4 etc. to the last cab file.Assemble your set and start the setup by booting the computer to a dos prompt.Change to 'A' dos prompt and run setup.You need 27 diskettes for Win95b or Win95c,21 diskettes for Win95a and 13 diskettes for Win95 first ed. Good luck.
I wouldn't recommend installing Windows 95 on a computer that came with XP unless you have a lot of experience with older operating systems on newer hardware and really know what you're in for. Otherwise, look around for a vintage computer with around 200 MHz or less. Or install Virtual PC on your XP computer and Windows 95 inside of that.
If your XP computer is not your main computer and you just want to experiment with it and see what happens, go ahead. It can be fun to fiddle around and see what's possible. But don't expect to get online with Windows 95.
