Will we be reunited with our family and friends in heaven? Yes, I have faith in God and I would really like to go to heaven after I die, not hell, no way! I trust in God and would like to see my family and friends in heaven after they die, only if they make it there. I would never, ever want to go to hell!
Although your question is not directly addressed in Scripture, we can draw some ideas from Scripture.

Revelation 7:17  For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes.
Rev_21:4  And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.

Since there will be no tears, death, sorrow, crying or pain in Heaven. Does it not follow that not seeing those we loved here on Earth would only cause us sorrow.

Revelation 20:6  Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Revelation 20:13 and 14  And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. And death and hell were cast into the lake of fire. This is the second death.

Here we see that death is banished and will no longer be an inhibition, nor will it have any effect on those who are part of the first resurrection. the first resurrection is the resurrection of the faithful
and the second death refers to:

Revelation 21:8  But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.

These are those destined for Hell. Although these Scriptures do speak directly to missing any loved one who are not in Heaven, it makes it seem that we will not know that they are not there.
