When there are more planets in a house, it shows an area where the planets will play out their urges. This interaction happens when the planets is separated by a specific number of degrees. This is called 'Aspects' and it relates to the positions that the planets are in, in relation to each other. It tells us about the mutual interaction of their functions, whether harmonic, disharmonic, strong or weak. When planets are squared or opposed to each other, this can sometimes indicate that there may be significant challenges to overcome in these areas. Sometimes these oppositions can be invigorating and beneficial. Below is a chart of aspects with the keyword.

The formula to calculate the aspects and the relationships between the planets in a house is -
[Meaning of Planet #1] (Keyword of Aspect) [Meaning of Planet#2]


This does not complete the variables/elements in analysing the chart for we are just at the very tip of the iceberg. There are several more - which we will not touch at this point in time. However, I am currently working on a more Advanced Level and another one on Vedic Astrology for those of you who were able to grasp the subject and show keen interest in burrowing deeper.

Now, begin with the Sun and Moon - for they will be the most important influences in your chart. Locate the Sun, and then the House of your Sun. Read the meaning of your Sun, then the meaning of the Sign that it is in: then the meaning of the House it is in. Repeat it with your Moon and each of the planets. Locate the Aspects patterns of your chart.

As you keep going deeper, it keeps getting more and more complicated. The biggest lump would be to be able to see the whole picture rather than just pieces of the puzzle. Continue your learning and add pieces to the puzzle.

P.S. - There is a difference of 22° between Western and Vedic Zodiacs. Thus it is wise not to mix up the two and to follow either one of the two.
