Japanese 101. Need help in translation.?

[Confused...]

I'm having some difficulties with some words... I understand about 70% of the words in a sentence but i need there are just some words I don't quite get. I also tried looking it up in dictionaries to no avail.

If anyone can help me make sense of the sentence specially the words with question marks next to it, I'd truly appreciate it.

1.) nantooka (?) no uma (horse) to issho (together?) no futari (2) no kaubooi (cowboy)

2.) ittoo (1?) no uma (horse) to issho (together?) no kaubooi (cowboy)

3.) kuruma (car) yorimo (?) basu (bus) no hou (?) ga ooi (many) desu

4.) uma (horse) yorimo (?) hito (person) no hou (?) ga sukonai (not as little?) desu

5.) What's the difference between:
onnanoko yorimo otokonoko no hou ga sukonai desu
otokonoko yorimo onnanoko no hou ga ooi desu

thanks in advance
