So why haven't you posted them ?
1. 6-methyl-6-propyl-2,4,7-nonatriene
2. 6-ethyl-3,6-dimethyl-1(1-methylpropyl)cyclohexa-1,2-ene-4-yne or 6-ethyl-3,6-dimethyl-secbutylcyclohexa-1,2-ene-4-yne
3. 4(2,2-dimethylethyl)-7(1,1-dimethylethyl)-5(1-methylpropyl)decane or 4-isobutyl-5-secbutyl-7-tertbutyldecane
4. 1-butyl-3,2-dimethyl-5-propylcyclohexane
5. 3-ethyl-7-ethyne-9-methyldeca-5-ene-1-yne

Time for the first two, got called away now.

1 Why not 4-methyl-4-propyl-2,4,7-nonatriene ?

2 1-methyl-3-sec-butyl-4methyl-4-ethyl-cyclohexa-1,2-ene-5-yne

2 1-methyl-3-sec-butyl-4methyl-4-ethyl-cyclohexa-1,2-ene-5-yne

The first problem can't be 4 because it would be 4-methyl-4-propyl-2,5,7-nonatriene we must give priority to the numbers for the bonds than to the alkyls, so it is 6-methyl-6-propyl-2,4,7-nonatriene

And the second problem same thing, the numbers in the bonds are priority.
