Short answer. Under this text, no — as written, only 'the guardian, other than a parent' may be allowed expenses and compensation, up to fifteen percent of the ward's net income. But because your ward is a minor, this Rules of Court provision no longer governs; the 2003 Rule on Guardianship of Minors is the law that currently applies to your situation.
What the law says
the guardian, other than a parent, shall be allowed the amount of his reasonable expenses incurred in the execution of his trust and also such compensation for his services as the court deems just, not exceeding fifteen per centum of the net income of the ward.

What Section 8 says about compensation
Rule 96, Section 8 requires a guardian to present an account to the court for settlement, and then addresses what the guardian may be allowed for expenses and compensation. It states that the guardian, other than a parent, shall be allowed the amount of his reasonable expenses incurred in the execution of his trust and also such compensation for his services as the court deems just, not exceeding fifteen per centum of the net income of the ward. On its face, this text limits the compensation allowance to guardians who are not parents.
Why the text singles out 'other than a parent'
The phrase 'other than a parent' is doing the work that answers your question directly under this text: it carves parent-guardians out of the group entitled to compensation for services, leaving that allowance for guardians who are not the ward's parent. Reasonable expenses and a percentage-based fee, capped at fifteen percent of the ward's net income, are described as available to the non-parent guardian specifically, not framed as a general entitlement every guardian automatically receives.
Why this provision isn't the current rule for your situation
Here is the complication for your situation, though: this Rules of Court provision is no longer the governing rule where the ward is a minor. A.M. No. 03-02-05-SC, the Rule on Guardianship of Minors, effective since May 1, 2003, took over guardianship of minors from Rules 92 to 97 of the Rules of Court, and the text above is now read as the rule for guardianship of incompetents who are not minors. Since you are managing your minor child's property, the 2003 Rule, not this section, is the current law that actually governs your guardianship.
What this means practically
What that means practically is that this article's parent-versus-non-parent distinction on compensation cannot be relied on as the current, controlling text for a minor's guardianship, even though it may reflect the same underlying approach. Anyone in your position — a parent serving as guardian of a minor child's inherited property — should look to the 2003 Rule on Guardianship of Minors for the rule that actually applies, rather than to this Rules of Court section.
