Help with small sentence(s)

Hi all, I have a speaking test in my japanese class coming up soon and for it I have pretty limited vocabulary as we can only use what we've learned in our book or learned in class. I'm making a guide for it to study off of and I think I messed this part up a lot..

1. Turn right at the traffic light.
2. Go straight past 2 intersections.
3. Family's house is ahead of restaurant.

1. しんごうをみぎにまがって、ふたつめまっすぐいきます 。
3. レストランのさきでかぞくのうちあります。
(obviously putting 1 and 2 together, might separate it later though)

Please note there's a lot of advanced/intermediate vocabulary I can't use.
Thanks in advance.

You're doing a good job though there seem to be some confusion on particles...

When showing the way to someone, you usually use ～(て)ください.

1. Turn right at the traffic light.
2. Go straight past 2 intersections.
1. しんごうをみぎにまがって、ふたつめまっすぐいきます 。

１．しんごうをみぎにまがってください。
２．まっすぐいって、こうさてんをふたつとおりすぎて ください。

3. Family's house is ahead of restaurant.
3. レストランのさきでかぞくのうちあります。

３．レストランのさきにうちがあります。

で is used to indicate the place where action is taken/some activities goes on while に is used with the verbs such as ある いる.
"Family's house" means your (speaker's) house?
Then you can simply say うち or わがや (my home).
When you say かぞくのうち, the listener would wonder whose family's home, or think you're talking about a house which belongs to one of your family members but not yours.
