Different creatures have different numbers of chromosomes; chromosomes are always diploid, or found in matching pairs. The number of chromosomes is in no way related to the complexity of the organism. For instance, fruit flies have eight chromosomes, humans have forty-six, butterflies have 380, and ferns have a remarkable 1200 chromosomes.
The truth is there is not really a direct correlation between the two. There are examples where the number of chromosomes does seem to correlate with complexity. Humans for example (assuming we are "complex organisms") have 46 chromosomes. Fruit flies have 8 and peas have 14. But, this is not the real story. Certain fish (Carp for example) have over 100 chromosomes. Shrimp actually have 254 chromosomes. Ferns have over 1200!
Yes it also relates to the uniqueness of how an organism looks (ex. Most frogs look alike meaning they have less chromosomes.)
There is no such relationship.
All cells within an organism will have the same number of chromosomes, which is the diploid number. The gametes, on the other hand, will have the haploid number of chromosomes.
No. Chromsomes are subject to breakage and fusion over evolutionary time, which can result in an increase or decrease in chromosome number, and the forces behind that are independent of an organism's size.
No there isn't. Humans are much more complex than a fern, yet the Adder's Tongue Fern has 1262 chromosomes and a human has only 46. It also doesn't work the other way either (more complex organisms having less chromosomes) for fruit flies have 8 chromosomes and dogs have 78. Also, chimpanzees have the same number of chromosomes as potatoes and, surely, they are on different complexity levels.

It depends on the animal. Humans have 46 chromosomes. Goldfish have 94. The number of chromosomes is not relative to the complexity of the organism.
Same number of chromosomes
Gametes have half the number of chromosomes that most cells in the organism have. Most human cells have 46 chromosomes, but eggs and sperm have 23 chromosomes each.

The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.

The number of chromosomes in a somatic cell.

There is no such number, depending on the organism the number of chromosomes varies from 1 to about 30,000,000!
