The structural model of C3H8 should include bold and dashed bonds to show different planes. Bold is used for coming out of the page or screen and dashed is used for going away.
C5H8 has 2 degrees of unsaturation (a saturated 5-carbon alkane would have 12 hydrogens, so 4 hydrogens, are removed to get to 8). A degree of saturation could be offered by a ring or a double bond (or two degress directly from a triple bond).
Some examples would be cyclopentene, with one ring and one double bond; pentadiene, a straight chain with two double bonds; pentyne (1-pentyne or 2-pentyne), with one triple bond; or even a spiro compound, spiro[2.2]pentane. There are other possibilities, by just varying how you combine double bond(s) and/or ring(s).

The three main types of isomers are structural isomers, geometric isomers, and enantiomers.
These are not optical isomers they are functional group isomers a subcategory of structural isomers.

None, as it has 5 structural isomers in which none of are optically active.
Molecules with the same molcular formulae but differing structural formulae are called isomers.
Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
