no, homologous chromosomes are only found in diploid 

i'll try and explain 

our diploid cells contain one chromosome from each parent 
so we all have 2 copies (homologous) of each autosomal chromosome and one sex chromosome from each, so XX or XY 

so 23 pairs (22 autosomal, 1 sex) 

however meiosis I separates homologous chromosomes and thats why cells become haploid 

and two haploid cells fuse to form a diploid zygote
