• 分ぶんJLPT N3approx.Common

  これが君きみの分ぶんのケーキだよ。↗

  Here is your share of the cake.
• 量りょうJLPT N3approx.Common
  noun, noun (suffix)Means quantity or amount, so it fits 'portion (of food)' only in the sense of how much food is served. It is really 'amount', not 'a serving'; use it when quantity is the point.

  She has had quite a lot to drink.
• 分け前わけまえCommon

  Let's agree to share in the profits.
• 箇所かしょJLPT N2approx.Common
  nounMeans a place, point, or spot, so it suits 'portion' mainly when referring to a passage or location within a text. It is not used for shares of food or money.
  この湖みずうみはこの箇所かしょが一番いちばん深ぶかい。↗

  The lake is deepest at this point.

For a part of a whole, use 部分; for an allocated share, 分 or 「分け前」; for food quantities, 量; for a place or spot in a text, use 箇所.
