It depends on how much capacity your ipod has and how much space the app takes up, you can keep track of how much free space you have on your ipod by clicking your ipod on the sidebar in itunes when it is connected. As many pages as you want. If you run out of space (gigabytes) then your iPod cannot have any more apps on it.
If you are referring to the 5th generation of the iPod Classic, you cannot play Roblox games on it. However, if you are talking about the 5th generation of the more commonly known iPod Touch, then yes it will be able to play Roblox games, however do note that it may not be able to play more advanced games due to its hardware.
you have to get the app glow backround or topping. (there's lots more but those are the ones i have) Edit: You can only do this on certain iPod Touches (i.e. 3rd and 4th Generation.) You would go to the Photos app and set the photo as the background image.
