Tooth count - the number of teeth on the chainring(s), the higher the number the harder the gear.
Chain width - some single chainsets will only work with a thicker 1/8” chain, all other chainsets take a standard 3/32” chain.
BCD - the distance between the chainring bolts, you’ll need this if you want to change rings.
Speed* - the number of cogs at the back the chainset was originally designed to be used with. You can happily mix different speeds, it’s just worth noting that the bigger the difference the more likely you are to experience shifting issues. As a rule of thumb, one or two speed difference shouldn’t be a problem, unless the chainset is for 10 speed or higher - these usually need the correct speed chain to avoid problems.
Pedal threads - this is usually stamped on the pedals. The standard thread is 9/16” x 20 tpi which almost all bikes use, the exception being older French bikes, bikes with one-piece cranks and Shimano’s Dyna Drive system - these are not interchangeable.
Bottom bracket type - ‘square taper’ bottom brackets, as the name suggests, have a square shaped axle that slots into the chainset. These are interchangeable between brands as long as you stick to the same axle length & profile. With all the other brand specific systems such as Shimano’s Octalink you must stick to the matching bottom bracket type.
